Tropical Storm Eta is forecast to move into the Atlantic by Thursday evening. Windy conditions, as well as scattered to isolated thunderstorms are forecast along the path of Eta. Localized bands of heavy rainfall will continue to impact portions of the Florida Peninsula on Thursday, resulting in isolated flash and urban flooding, especially across previously inundated areas. Minor river flooding is expected across portions of West Florida lasting into the weekend. Moderate to heavy rain, associated with Eta, will produce an additional 1 to 2 inches of rain across portions of the Florida Peninsula through Thursday evening. Isolated maximum storm total accumulations of 20 to 25 inches are forecast over South Florida and will let up later Thursday evening as the storm moves into the Atlantic. A front draped north of Eta, will move offshore by Thursday evening producing heavy rain over the Mid-Atlantic and the Southeast. There's a Moderate Risk of Excessive Rainfall leading to Flash Flooding over the Mid-Atlantic as the heaviest bands of rain push through that region by Thursday evening. Meanwhile, a front will move into the Pacific Northwest and continue to move eastward to the Middle Mississippi Valley by Saturday evening. The system will produce coastal rain and higher elevation snow over the Northwest. Overnight Thursday, the snow will move into the Northern Intermountain Region and into the Northern Rockies. Higher elevation snow and lower elevation rain will move into the Great Basin overnight Thursday, too. In addition, strong gusty wind will develop over parts of the Intermountain Region into the Northern/Central Rockies by Saturday evening. Heavy high-elevation snow is a concern for the Cascades and Northern Rockies producing 1-2 feet of snow, likewise, through Saturday evening. The snow will produce hazardous driving conditions across the area. Ziegenfelder Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
